Rosemount™ SeniorSonic 3414 Four-Path Gas Ultrasonic Flow Meter

Preferred for fiscal gas measurement, this 4-path meter delivers high accuracy and fast diagnostics with British Gas-chordal design and 3410 electronics.

The Rosemount™ SeniorSonic™ 3414 Four‑Path Gas Ultrasonic Flow Meter delivers high‑integrity custody transfer measurement with ±0.1% flow calibrated accuracy and advanced diagnostics that detect flow disturbances, liquids, and buildup early. Continuous Flow Analysis and Smart Meter Verification provide actionable insights to reduce uncertainty, protect revenue, and ensure reliable, audit‑ready performance in real‑world conditions.​

Key Features

  • Detect flow disturbances early with a 3D flow profile view that reveals swirl, asymmetry, crossflow and turbulence for faster troubleshooting.​
  • Maintain custody transfer accuracy using continuous diagnostics that identify liquids, buildup, and abnormal flow conditions before bias occurs.​
  • Increase operational flexibility with >100:1 rangeability to support wide flow conditions with fewer meter runs. ​
  • Automate compliance with integrated AGA 8 and AGA 10/GERG-2008 calculations for consistent, audit-ready gas measurement.​
  • Reduce measurement uncertainty with predictive alerts that flag blockage, contamination, and changing gas conditions.​
  • Minimize downtime with non-wetted transducers that can be replaced under pressure without special tools.​
  • Lower total cost of ownership with no moving parts and zero pressure drop to reduce maintenance and compression costs.​
  • Simplify troubleshooting with Smart Meter Verification that converts diagnostics into actionable insights and recommended actions.​
  • Enable flexible integration with high-speed electronics offering Ethernet connectivity and multiple I/O options.​
